Data transfer between scenes — iOS App

This topic is pretty important for me and you, because transfer data between scenes happens all the time when using a app, so we have to learn it well for sure.

In my example, I will use segue to send data to next scene, when it comes to return previous scene, I will use notification. Today’s challenge is to make a list, the data of lists will send to next scene, and there is a editing scene, if we changed the content of lists, the data of previous scene will be changed too.
